#42 of 61 1997 Deville does not crank nor start
Dec 07, 2009 (9:35 pm)
I'm new to this forum. I'm looking at a 1997 Deville for sale very inexpensive. The catch: The current owner said it was running great and then the digital dash went blank (off) and the engine quit. The car will not crank or anything. He has only one key and thinks it might be the computer chip in the key. Is this possible or is it possibly a real risky deal? I do not know how many miles it has on it yet, but it looks good. Thanks, George
#43 of 61 New Engine???
Dec 07, 2009 (9:51 pm)
My '89 Coupe de Ville with 77,000 miles apparently has a blown head gasket. (It tested positive for hydrocarbons in the coolant. 85!) I'm told to either get a rebuilt or a used engine. Think I'm throwing good money after bad? Is there no "easy" way to take the heads off and replace the head gasket? It's obviously not like the good 'ol days when you could do it in your garage on Saturday morning. I can't seem to find anyone that wants to tackle the job. Everyone says $1500 to $2000, or more! Any suggestions?

First thing to check is both battery cables. Check where both are bolted down, both ends. Check that there is not extensive corrosion INSIDE the rubber insulation. A cable can rot away inside there where it cannot be seen.
Next place would be the security system. I think this year had a lot of problems with a small wire inside, or at the bottom, of the steering column that breaks. This is the wire that takes the signal from sensing the small 'pellet' in the key to the system that controls the security system.

Will this work on a 96 4.6 deville also? keeps saying service emissions, rough idle but runs good.
#47 of 61 2001 cadillac dts idle problems
Jan 13, 2010 (5:51 pm)
i have a 2001 dts 78,000 miles serviced regularly at dealership, noticed lately idle is low at start up sometimes, within a month car refused to start twice because idle was at about 400 to 500. sometimes while driving idle will be high around 1500 to 2000 with foot off gas pedal and u can feel it pulling at a complete stop. sometimes car runs fine with no problem. check engine light came on and the codes were 506 and 507. ive cleaned throttle body but not iac also was wondering if it was a vacuum leak could the idle fluctuate both low and high idle sometimes??? please help with any suggestions. thank u very much
#48 of 61 '98 concourse wont start

when I try to start I get a message, "Starting disabled, wait 3 minutes". Sometimes it works, sometimes not. Is this the chip in the key or the computer going out or something else.
#49 of 61 2000 Deville will not crank
Dec 01, 2010 (4:18 pm)
Hello gang. I have been trying to get an answer to this problem for about a month now from all over. My 2000 Deville (Base) will not crank. Everything works, battry new, replace key cylinder, crank sensor A & B, ignition switch, starter and starter relay, and check all connections and grounds (to the best of my knowledge). There appears to be a break down between the starter and gound. If you connect a separate ground from body to starter the engine will turn over slowly. If you run the additional ground to the body, it barely turns the engine over I used jumper cables and also tried at the battery ground. The only codes were P0335, P0340, P0385, which all point to to crank and cam sensor curcuit, all of which seem to have tested fine. Even used a scan tool not a Tech 2 (loaded with updated software, except for the GM high priced subscriptions) a friend has, but could not get a crank request. Any help would greatly be appreciated. I do have the factory service manuals.

You've thrown a lot of parts at this problem without much success. I think it's about time to tow it to a dealer.
A problem with my wife's 2005 Deville - I like to bring up all the displays occasionally. The voltage was continusly bouncing between about 13 and 15.5 volts. Staying on any voltage only a few seconds.
What I found was the negative battery cable, under the read seat, grounds to the body there, right next to the battery. It was a little loose, plus the red paint (car color) was under the cable. I removed the bolt, ground the paint off with a Dremel tool, and scraped the cable end, etc. This totally stopped the voltage bounce.
If you haven't done it, you sure need to check this battery ground back there!
